However, if you want to use ntfs-3g to mount the NTFS filesystems anyway, create a symlink for mount command: ln -sv.. Command Explanations --disable-static : This switch prevents installation of static versions of the libraries.

Contents Installed Programs: lowntfs-3g, mkfs. Installed Library: libntfs-3g. Short Descriptions lowntfs-3g is similar to ntfs-3g but uses the Fuse low-level interface mkfs. NTFS is also an excellent choice and a popular file system on external hard-disk drives with large storage capacities because it supports large partitions and big files.

What is NTFS sparse files support? Category: technology and computing operating systems. When a program accesses a sparse file , the file system yields allocated data as actual data and deallocated data as zeros. NTFS includes full sparse file support for both compressed and uncompressed files. What is the purpose of NTFS? What are the advantages of NTFS?

Advantages and Disadvantages. What is GPT format? What is NTFS and how does it work? What is the difference between fat32 and ntfs? What is the current version of NTFS? The holes are always read as zeros. As of today Linux provides inadequate support for managing tar, cp, gzip, gunzip, bzip2, bunzip2, cat, etc large sparse files. However none of the common utilities supports it. This means when you tar, cp, gzip, bzip2, etc a large sparse file they will always read the entire file, even if you use the "sparse support" options.

Moreover neither of them handles large sparse files efficiently during uncompression from disk space usage point of view. At present the most efficient way, both speed and space-wise, to compress and uncompress large sparse files by common tools would be using tar 1 with the options -S handle sparse files "efficiently" and -j filter the archive through bzip2.

Although tar still reads and analyses the entire file, it doesn't pass on the large data blocks having only zeros to filters and it also avoids writing large amount of zeros to the disk needlessly. But since tar can't create an archive from the standard input, you can't do this in-place by just reading ntfsclone standard output.

Even more sadly, using the -S option results serious data loss since the end of and the GNU tar maintainers didn't release fixed versions until the present day. It's also possible, actually it's recommended, to save an NTFS filesystem to a special image format.

Instead of representing unallocated blocks as holes, they are encoded using control codes. Thus, the image saves space without requiring sparse file support. The image format is ideal for streaming filesystem images over the network and similar, and can be used as a replacement for Ghost or Partition Image if it is combined with other tools.
